To @ZZ whom, it muy con/cera.-

Be it known that I, IIIJNRY A. lIOUsE, a

Bridgeport, in the county of Fairfield and State of Connecticut, haveinvented certain new and useful Improvements in Vapor- Ilurners, ofWhich the following is a specificallIy invention relates to that classof vapor.- burners in which there are ports and valves which are liftedas the pressure of the vapor increases; and my invention consists incertain improvements fully set forth hereinafter, and illustrated in theaccompanying drawings, in Which- Figure l is a sectional elevation of avaporburner embodying my improvements.

ignitenseetions. Fig. 3 is a section on the line 3 3, Fig. l. Fig. et isa sectional elevation showing a modication.

The burner A, of suitable construction, is combined with. a generator B,also of suitable construction, which has a chamber or channel it, withwhich communicates a pipe 5, havingl a cock 6. This pipe 5 maycommunicate with an oil-reservoir or it may communicate other suitablesource of supply. As shown, the burner A has a easing 8, whichcommunicates through a pipe with a chamber in the generator B, and whichhas a port 9,to which is fitted av valve D. The stem of the valve,however, instead of extending into the easing, slides upon a spindle orguide l0, projecting from the casing, as in Fig. l, or it may beotherwise guided, as, for instance, in Fig. 4l, hereinafter described.In either case the casing 8 may be made very small, as it need be ofonly sufficient dimensions to contain the chamber for the reception ofthe gas which passes to the port 9.

In this class of apparatus it is common to provide the burner with anopening or port through which the gas Hows and of uniform dimensions. Anobjection to this construction is that the gas is generated underdifferent circumstances under different pressures, and an openingadapted for one pressure and for a flame of one degree of efflciency isnot adapted for another pressure and a 'flame which should be of adifferent Serial No. 539,760. (No model.)

degree of efficiency; and in order to correct this effect I have inLetters Patent No. 533,593, granted to myself and II. A. House, Jr., setforth a construction wherein there is a movable Weighted valve Whichwill rise in proportion as the pressure increases, so as to afford alarger opening` and permit a larger flame when a burner of greaterenergy is required. This has proved to be a greatimprovement upon thekind of burners previously made, but it is not capable of awide range ofaction. Thus if but a small portion of oil passes to the generator andgas is generated in small quantities at a lorv pressure the valve maynot be raised to any perceptible extent, Whereas if the gas is generatedat a very high pressure it may be raised to too great an extent, and theweight of the valve has therefore to be proportioned to a somewhatlimited capacity.

In order that the burner may operate with equal efficiency Whether thegas is so admitted as to constitute aburner of five horse-power or fiftyhorse-power, I provide a number or series of Weights which may bebrought successivelyinto action to load the valve in proportion as it israised higher, so that it will move under the action of one Weight andbe very sensitive to low pressures and under the action of all theWeights when the pressure increases to a maximum'.

The series of weights, or the equivalents of the same would be a seriesof or variable springs, may be combined with the movable Valve invarious different Ways so as to secure this result.

In the construction shown in Fig. e there are a series of concentricWeights w 'w' 102, arranged around and guided by the easing S of theburner and by each other, and the valve D is connected by a cross-bar toarms of the inner Weight 102, which can play freely to a limited extent,but upon the valve being raised beyond a given point the Weight 'w2cornes in contact with a lip 20 of the Weight w', and When the latterhas been limited to a further extent it comes in contact with a lip 2lof the Weight w, so that there is an increase of Weight upon the valvein proportion as it is raised higher.

It will be obvious that any other suitable IOO connection may be madewhereby the weights are successively brought to bear upon the valve inproportion as it is raised higher.

Another arrangement is illustrated in Fig. 1, where the valve-stem 14carries an igniter E, arranged below a block 17, extending through anopening in the easing of the generator and connected with a ring 19, thestem of the valve being of such a length that after the valve raises fora certain extent the stem of the valve will make contact with the block17 and the weight of the latter will be added to the valve. Above theblock 17 and ring 19 is a concave perforated disk 18, which rests upon aring F above the generator a short distance above the ring 19, so thatafter the latter is raised for a certain extent the weight of the disk1S will be added to that of the ring 19 and to the valve.

The parts E, 17, 19, and 1S are all ol' refractorymaterial, so thatafter they have become th oro u ghly heated by the flame they will serveas igniters in case the llame is extinguished. It will be observed alsothat said several parts are disposed in proximity to the burner andgenerator with some part or branch projecting or extending into thespace surrounding said burner and generator.

It is very apt to be the case with the character of oil that is usedwith. such burners that there will be at times portions of water mixedwith the oil, and these vaporizc in the generator, so that steam passesto the burner, and for a short lengt-h ot time, from one to five or tenseconds, the passage of ignitible vapor is interrupted and the flame isextin guished. By arranging in. proximity to the burner a mass ofrefractory material, as, for instance, baked clay, which becomes veryhighly heated in the presence of the flame, the temporary extinguishingof the 'llame is accompanied with no injurious results, as therefractory material will remain in an incandescent statc for severalminutes, so that when the oil again passes to the generator and isvaporized and passes from the burner thc vapor will be ignited, and byhaving the refractory material at several different points the vapor maybe ignited at one point, if not at another. 'lhus in the constructionshown in Fig. 1 the refractorymaterial in three dif- 'ferent sectionsserves not only as an ignitcr for the vapor which may pass to differentpoints of the apparatus, but also serves as a succession of weightsabove the valves. The refractory material may be in different shapes. Asshown, the portion or section E has a central hub receiving the stem ofthe valve and with radiating ngers 16, and rests upon an adjustable ring12 upon the valvestem, so that by raising or lowering this ring therefractory material may be brought in any desired proximity to theopenin to which the flame passes.

It will be seen that in the burner herein described there is no casingaround the mixing case or chamber, which is practically the space orchamber within which the burner is arranged.

It desired, the chamber may be restricted by an inclosing casing; butthe construction shown is preferable for certain purposes, as, forinst-ance, in snufting apparatus. The construction shown in Fig. 4 isespecially adapted for such apparatus, in which case the generator wouldnot be arranged above the burner, as in Fig. 1, but a separate andindependent generator would supply the gas to the pipe 7.

I do not here claim, broadly, the arrangement of successive weightsbelow the burner, as illustrated in Fig. 4, as this constitutes thesubject of a separate application for Letters Patent. Nor do I describeor claim the particular construction illustrated of the genera-- tor, asthis also constitutes the subject of a separate application for LettersPatent.
